Because the construction area of water conservancy monitoring equipment covers a wide range, some may even be built in remote mountain areas, and face severe weather such as storms and rain. Therefore, there are many tests for practical application and construction. Problems and solutions in the construction of water conservancy security monitoring So what problems do engineers and users often encounter? What better solutions do they need? Unclear picture of harsh outdoor environment Q: The construction environment of water conservancy monitoring equipment, Most of them are exposed to the harsh outdoor application environment for a long time, so they often face severe tests. And because the river covers a wide range, and the upstream area is located in a sparsely populated wilderness, the number of street lights is usually small. Therefore, some cameras installed on the upstream of the river can obtain clear images when there is sufficient light during the day, but when the sky is dark at night, Faced with the problem of insufficient light, it is impossible to capture clear images. In stormy weather, if the rain is too heavy, it will also affect the camera's line of sight. Only blurred images can be collected. Even if the video image can be successfully transmitted to the centralized control center, the administrator cannot see a clear image. Although the camera is equipped with a small wiper in front of the lens, this problem cannot be completely solved. A: In the project design and planning, it is recommended to match auxiliary light sources such as traditional lights, infrared lights, and spotlights. However, because the monitoring range is too large, if the shooting distance is too far away, the supplementary light effect is not good, and the image will still be unclear. It also wastes high costs. Therefore, in addition to paying attention to the height and position of the light source when it is necessary to install an auxiliary light source, it is more important that the low illumination of the camera must be a certain level when purchasing. When the night vision effect of the camera is sufficient, it is good...
